Digital cameras providing useful images now start below $400. Companies are
simply taking pictures of stuff and loading those pictures directly into
computers for use in
Desktop Publishing to produce documents of all kinds, including catalogs,
asset records, advertising material, etc. The images are also used in
HTML documents for Web pages on Internet and
The use of digital images is further extended by using Object Databases which allow pictures to be embedded right in the database data records with other data types. Other uses including being able to email pictures to people as attachments, which is much faster than the mail, and the images are ready for the receiver to store on hard disk or include in digital documents.
Many current cameras have removable storage media that can hold hundreds of pictures (depending on resolution), and some can "certify" the images to assure they have not been tampered. This is essential for insurance and evidence work as digital images are so easy to modify.
Cautions: you should not expect true photographic quality from an economical digital camera. Even the most expensive digitals can't produce the quality of a good film camera, but they can be highly useful within their limitations. Be aware also that the better the image the more disk storage space it takes up. Be sure you understand the storage needs before starting a project.
